IMovie '08 has much higher system requirements than the rest of iLife '08: It requires at least an Intel or G5 processor (the rest of the package will work with a G4), and in the latter case, it requires at least a dual 2-GHz PowerMac or a 1.9-GHz iMac. (It's not the CPU itself that matters, says Apple, but the GPU, but it's easiest to identify an iMovie-capable machine by its CPU configuration.) For all these reasons, it's a good thing that the iLife installer leaves the previous version on your hard disk (adding the new version next to it) when you upgrade the rest of the suite. Apple has also made iMovie 6 available as a free download. Note that while iMovie '08 can import projects created with iMovie 6 and earlier, iMovie 6 cannot work with iMovie '08 projects unless they are exported as a QuickTime file.
